Learn CodeIgniter 4 API Development Using JWT Authentication

Kick off API development without authentication by setting up CodeIgniter 4, installing dependencies, and creating employee management endpoints—create, list, detail, update, and delete—via migrations.

Create a migration file to define an employee table with id (primary key, auto increment), name, email (unique), and profile image (nullable). Migrate to create the table and enable rollback.

Create a restful employee controller and a corresponding employee model in CodeIgniter 4, implementing create, list, detail, update, and delete APIs with database connectivity and mass assignment rules.

Learn to create api routes in CodeIgniter 4 using a route group and coordinator, defining endpoints for create, list, detail, update (spoofed post to put), and delete employee.

Create and save an employee data API in CodeIgniter 4 by validating form data, uploading an optional profile image to public/images, and saving to the employee model.

Test the create employee API in CodeIgniter 4 by sending post requests with name, email, and optional profile image, observing validation, and confirming database insert.

Create a data api endpoint that uses a get request to list all employees from the database, returning a 200 response with the employee data via the find all method.

Develop a single data api that retrieves a detailed employee record by id using a CodeIgniter 4 model, the find method, and a get request with appropriate responses.

Learn how to implement a robust update employee API in CodeIgniter 4, including form data validation, optional profile image upload, image renaming with timestamp, and updating records with proper responses.

Implement a delete data API using a delete request with an employee ID, verify existence via the employee model, delete when found, and return a 200 response.

Develop a phase of CodeIgniter 4 API development using basic authentication, implementing category and blog modules with migrations, and create, list, update, and delete endpoints secured by static credentials.

Install and configure the second phase of the development setup with the composer command, prepare the database, adjust the setup files, and start the local server to complete the installation.

Create migrations to build categories and blogs tables in CodeIgniter 4, defining id, name, and status with an enum 0/1 defaulting to 1, plus blogs with category_id, title, and content.

Explore creating a CodeIgniter 4 api controller with restful methods for create and list categories, and create, list, detail, update, and delete blogs using post, get, put, and delete requests.

Create models for category and blog tables and implement a basic authentication filter in CodeIgniter 4, wiring the Spark generated files and registering the filter to secure API requests.

Configure grouped api routes in CodeIgniter 4, using a namespace for api controllers, to create and list categories and blogs and manage single, update, and delete operations.

Learn how to create a category API in CodeIgniter 4, including name and status validation, category model insertion, and returning success or error responses.

Implement basic authentication in a CodeIgniter 4 API by using a before filter to decode base64 credentials from the authorization header, validate them, and deny access if invalid.

Create a list category API in CodeIgniter 4, returning all categories in JSON using the category model's find all method, secured by basic authentication with a base64-encoded header.

Create a blog API by validating category id, title, and optional content, verify category existence, and persist the new blog using the blog model, returning success or error messages.

Learn to build a list blogs api in CodeIgniter 4 using the query builder and inner join with categories to return id, category_id, title, content, and category name.

Fetch a single blog detail by its id using CodeIgniter 4's query builder, joining the blogs and categories tables to return the blog data with the category name.

Verify the blog exists, validate category id and title, and update blog details through the update blog api. Ensure category exists and test via postman with method spoofing to put.

Implement the delete blog API in CodeIgniter 4, validating blog existence before deletion and returning success or not found under basic authentication, with JWT in a future phase.

Explore building a CodeIgniter 4 API with JWT authentication, including user registration, login, and protected endpoints like user profile and books management, using migrations and a JWT package installation.

Set up a CodeIgniter 4 API project and install the JWT composer package to enable authentication. Understand JWT structure and encode/decode methods for secure tokens.

Create migrations to build the users and books tables in a CodeIgniter 4 project, defining id, name, email, password, and book title and price, then run the migrations.

Create a restful API in CodeIgniter 4 with controllers and models for users and books, enabling register, login, profile, and book create, list, and delete via JWT secured routes.

Create api routes under the api namespace, binding register, login, and profile endpoints to the api controller, and add book routes for create, list, and delete using appropriate http methods.

Create a register user API in codeigniter 4, validate name, email, and password with a unique email, hash the password, insert into the users table, and return success or error messages.

Learn how to build a user login api in CodeIgniter 4 using JWT authentication, including email and password validation, password verification, and token generation.

Learn to build a CodeIgniter 4 user profile API that accepts a JWT from the authorization header, decodes its payload, and handles token expiry and errors to fetch profile data.

Create a book API in CodeIgniter 4 with JWT authentication. Validate title and price, decode the token for user id, and insert the book using a reusable method.

Learn to build a list books API in CodeIgniter 4 using JWT authentication, decoding the token to fetch and return all books created by the authenticated user, with error handling.

Develop a delete book API using a delete request with book id and JWT authorization to verify ownership, delete the record, and return 200 or 404.

Learn how JWT authentication handles user logout without storing tokens, and how setting token expiration provides automatic destruction after a defined period in CodeIgniter 4 API development.
